Background/Objectives: Several independent studies have associated prostate cancer (PCa) with specific groups of bacteria, most of them reporting the presence of anaerobic or microaerophilic species such as Cutibacterium acnes (C. acnes). Such findings suggest a prostate cancer-related bacterial dysbiosis, in a manner similar to the association between Helicobacter pylori infection and gastric cancer. In an earlier exploratory study looking for such dysbiosis events, using a culturomics approach, we discovered that the presence of obligate anaerobes (OAs) along with C. acnes was associated with increased prostate-specific antigen (PSA) levels in 39 participants. Methods: Building on this, in this study, we analyzed 89 post-rectal examination urine samples, from men with prostate cancer attending the PROVENT trial, using 16S rDNA sequencing. Our investigation focused on the impact of six previously identified OA genera (Finegoldia, Fusobacterium, Prevotella, Peptoniphilus_A, Peptostreptococcus, and Veillonella_A) on PSA levels. However, an additional data-driven approach was followed to uncover more taxa linked to increased PSA. Results: Our analysis revealed a statistically significant association between Peptostreptococcus and elevated PSA levels. Additionally, there were potential interactions between Prevotella and Fusobacterium. Interestingly, we also found that an aerobe, Ochrobactrum_A,was significantly linked to higher PSA levels. Conclusions: These findings suggest that OA-related dysbiosis may contribute to elevated PSA levels through prostate cell damage even before prostate cancer develops, possibly playing a role in chronic inflammation and the hypervascular changes seen in precancerous lesions. Future clinical trials with larger cohorts are needed to further evaluate the role of OA in prostate cancer development and progression. Full article

Sexual and reproductive health (SRH) is essential for men’s health, but a large body of research has indicated that the underutilization of most SRH services by men is a persistent issue that needs to be addressed. Men’s reluctance to access sexual and reproductive health services is one of the factors that leads to high morbidity and mortality rates among men, although their diseases may have been prevented or cured. This study aimed to explore factors that influence the decision of men who resided in men’s hostels and who accessed urology clinics in KwaZulu-Natal to seek help for their sexual and reproductive health issues. An exploratory qualitative approach was adopted using focus group discussions. We interviewed seventy-two men of ages above 15 years. The data were analyzed thematically. The Biomedical Research Ethics Committee (BREC) of UKZN granted ethical clearance (BE 347/19). Of the 72 interviewed men, thirty-three men attended urology clinics in the selected hospitals, and thirty-nine men resided in the hostels around Durban in KZN. Seven themes (lack of awareness of SRH services; participants’ reluctance to access SRH services; influence of culture and religion; lack of financial resources; influence of relationship dynamics; perceived low risk of individual sexual behaviors; and healthcare factors that discourage men from accessing SRH services) emerged from the data that were identified as barriers to SRH service utilization by men, whilst three themes (healthcare enabling factors; access to general information on SRH services; and personal motivational factors) emerged as factors that encouraged the participants to access these services. The participants’ reluctance to access SRH services was attributed to the lack of awareness of available SRH services, the influence of culture and religion, lack of financial resources, relationship dynamics, the perceived low risk of sexual behaviors for individuals, and healthcare workers’ negative attitude towards men requiring SRH services. The availability of healthcare resources, the appointment of more male healthcare workers, and more positive attitudes among healthcare workers will encourage men to utilize SRH services. The exposure of various barriers to SRH service utilization by this investigation warrants urgent attention from the government to impart knowledge about this phenomenon to men. Full article

Adult Acquired Buried Penis (AABP) is a morbid condition that often requires surgical intervention. This retrospective study of 46 patients who underwent AABP surgery from November 2017 to July 2023 evaluates surgical outcomes, functional outcomes, and patient-reported outcomes. The median follow-up (FU) was 46 months. Patients were categorized by surgical complexity using the Pariser classification, with 76.1% undergoing high-complexity procedures (Pariser ≥ III). Common comorbidities included obesity (58.7%), prior circumcision (52.2%), and hypertension (52.2%). The low-complexity group had a shorter hospital stay (p = 0.02). No other significant differences were noted between groups in terms of Body Mass Index, operative time, or FU. Sexual dysfunction (45.7%) and urinary issues (38.1%) were the main reasons for surgical consultation. Skin grafting was required in 63.0% of patients; partial graft loss was more common in full thicknes skin graft group (p = 0.04). Postoperative complications occurred in 32.6% of patients, 13.3% of which were classified severe (Clavien ≥ III). The median increase in stretched penile length was 2 cm. The recurrence rate was 21.7%. The 12-month recurrence-free survival rate was 89.1%. All groups saw significant improvements in urinary and sexual function post-surgery (p < 0.05), and high patient satisfaction was reported (90.3%). Despite the complication rate, AABP surgery significantly improves quality of life, with ongoing advancements in technique anticipated to enhance outcomes further. Full article

In NT scholarship, the Paul Within Judaism approach has gained considerable momentum. In this approach to Paul’s discourse on identity, a distinction is drawn between “Jewish” and gentile followers of Christ. “Jewish” followers, including Paul, are considered those that remain fully Torah-observant, whereas gentile followers are regarded as not fully Torah-observant, especially with respect to circumcision. In this contribution, Paul’s identity in relation to first-century “Judaism” and/or historical Israel is reconsidered. The main question that is asked in this regard is whether the Paul Within Judaism approach is a viable position in light of the hermeneutical difficulties surrounding first-century “Judaism”, as well as Paul’s own rhetoric around the Ἰουδαῖοι (“Jews”/“Judaeans”). Another question that is asked is whether Ἰσραήλ (“Israel”) and the Ἰουδαῖοι point to the exact same entity. Would it be more accurate to see Paul as being within Israel as one of God’s covenant people than as remaining a Ἰουδαῖος (“Jew”/“Judaean”)? Or did Paul leave his identity as a Ἰουδαῖος or as part of Israel behind for a new identity to be defined around Israel’s Messiah only? Lastly, it is considered whether Paul’s discourse on identity leaves room for an identity in Christ that is inclusive of an identity as a Ἰουδαῖος or as being part of Israel, or whether the identity in Christ excludes the latter.

Lichen sclerosus (LS) is a chronic inflammatory disease of the skin, and the gold standard for treatment is the use of the very potent topical steroids, but they can have side effects. Previously, we demonstrated that OZOILE (stable ozonides) were effective in children affected by LS, reducing the inflammatory process and stimulating tissue regeneration of the foreskin, showing a similar efficacy to steroid treatment. In this study, the modulation of inflammatory and oxidative stress pathways was evaluated by qRT-PCR and Western blotting in foreskins affected by LS removed from patients untreated or treated with OZOILE or corticosteroid cream formulations for 7 days before circumcision. OZOILE induced a significant increase in NRF2 and SOD2 levels, while it did not produce change in MIF, NF-kB subunits, and MMPs in comparison to untreated foreskins. Conversely, steroid topical treatment produced a significant reduction in the expression of p65, MIF, and MMP9, but it did not cause variation in NRF2 and SOD2 levels. These results demonstrate that the use of OZOILE as cream formulation exhibits effects on NRF2 signaling, and it does not induce NF-κB activation, unlike corticosteroids. On the basis of our biochemical data, further studies evaluating the role of NRF2 signaling cascade are necessary. Full article

Background: There are numerous methods of circumcision performed worldwide, typically classified into two main groups: conventional surgical techniques and various device-assisted techniques. Each method has its own advantages, limitations, and potential complications. The aim of this study was to compare outcomes of the Alisklamp technique versus the dorsal slit technique in male circumcision procedures. Method: This multicenter RCT compared the dorsal slit and Alisklamp techniques for circumcision, assessing patient demographics and intraoperative and postoperative outcomes. All patients, under local anesthesia via dorsal penile nerve block, were discharged on the same day and followed up at 24–48 h, 1 week, and 1 month. Results: A total of 180 patients enrolled, and 166 patients were included. The study compared postoperative outcomes between the Alisklamp (AK) and dorsal slit (DS) circumcision techniques in 166 patients. Key findings included significantly higher penile edema in the DS group (19%) compared to the AK group (2.4%) (p < 0.001), with severe edema occurring only in the DS group. Wound gaping was more common in the AK group (8.3%) compared to the DS group (1.2%) (p = 0.030). Skin tunnels were observed only in the DS group (9.5%) (p = 0.004). There were no significant differences in nausea, vomiting, bleeding, necrosis, infection, wound dehiscence, chordee, rotational anomalies, or secondary phimosis between the groups. Mean operation time was lower in the AK group than the DS group (7.8 min vs. 15.5 min; p < 0.001). Conclusions: The Alisklamp technique is recommended as the preferred method for circumcision because it minimizes complications, shortens the procedure time, and is easy to apply. Full article

The exodus event demonstrates a culture and religious shift from an Egyptian context to that of national Israel. Scholars have underplayed the influence of Egypt on Israel during the exodus while overplaying the influence of Canaan. To be sure, Canaanite mores influence the practices of the Israelites. However, the generation that left Egypt (according to the Biblical account) would have been assimilated to Egyptian mores. Thus, the present article seeks to establish the exodus event as the means by which Israel sheds its former Egyptian mores and becomes “national Israel”. Full article

Circumcision is a long-standing and frequently performed surgical procedure which holds significant cultural significance among AmaXhosa people in South Africa. Due to cultural reasons in some parts of Africa, the integration of medical male circumcision with traditional manhood initiation rituals still lacks acceptance. This study examined the level of knowledge and acceptance of voluntary male medical circumcision (VMMC) among young males in a selected high school in the Nyandeni District of the Eastern Cape Province, South Africa. A descriptive, quantitative, cross-sectional study was conducted, and a self-administered questionnaire was used to obtain information on sociodemographic characteristics, knowledge of VMMC, perceptions of VMMC, and circumcision practices. One hundred participants were recruited from both grades 11 and 12, and 82% of the participants indicated that they had received information about VMMC. Most of the respondents (88%) preferred traditional male circumcision (TMC), and only 12% of respondents preferred VMMC. The participants displayed a good understanding of the distinction between VMMC and TMC. However, results from the study showed that most respondents exhibited low acceptability and knowledge towards VMMC. These findings highlight the need to develop evidence-based strategies to enhance learners’ knowledge and acceptance of VMMC. Full article

Background: Phimosis is the inability to completely retract the foreskin and expose the glans. The treatment of phimosis varies depending on the age of the patient and the severity of the disease; a great number of conservative or surgical treatments are currently available. Aim: To provide the first review summarizing the available options for the treatment of adult phimosis. Methods: A PubMed, Cochrane and Embase search for peer-reviewed studies, published between January 2001 and December 2022 was performed using the search terms “phimosis AND treatment”. Results: A total of 288 publications were initially identified through database searching. Thirty manuscripts were ultimately eligible for inclusion in this review. Conservative treatment is an option. and it includes topical steroid application and the new medical silicon tubes (Phimostop™) application for gentle prepuce dilation. Concerning the surgical approach, the gold-standard treatment is represented by circumcision in which tissue synthesis after prepuce removal can be also obtained with barbed sutures, fibrin glues or staples. Laser circumcision seems to be providing superior outcomes in terms of operative time and postoperative complication rate when compared to the traditional one. Several techniques of preputioplasty and use of in situ devices (which crush the foreskin and simultaneously create haemostasis) have been also described. These in situ devices seem feasible, safe and effective in treating phimosis while they also reduce the operative time when compared to traditional circumcision. Patient satisfaction rates, complications and impact on sexual function of the main surgical treatments are presented. Conclusion: Many conservative and surgical treatments are available for the treatment of adult phimosis. The choice of the right treatment depends on the grade of phimosis, results, complications, and cost-effectiveness. Full article

This article examines why Paul uses self-praise, or periautology, in Phil 3:2–14 to respond to Christians who boasted of their Jewish origin. It shows the importance and relevance of this type of rhetoric, clarifies its purpose, and examines the way Paul uses it. Paul does not only use periautology in Phil 3, but it is in this passage that it has the most force and originality. As, until now, very few monographs and articles have shown the existence of periautology in the Pauline letters, this article invites exegetes to be more sensitive to the existence of literary models and their importance for better interpreting the apostle’s thought.

The royalty of the Classic Maya of Mesoamerica, and later sages of the Maya, used a powerful diphrastic kenning chab akab’, glossed as “generation-darkness” to convey a range of objectives, conjuring foremost among them. Known principally from hieroglyphic written expressions, but also depicted in the form of sacrificial instruments and offerings, Eleanor Harrison-Buck, following Timothy Knowlton, proposed that the kenning references sexual intercourse. This essay proposes that a black steatite carved figure stylistically dating to the Middle Preclassic period (900–350 CE) depicts this incantation as an old woman giving birth to her maleness in the form of a circumcised penis. A second Middle Preclassic figure of a dancing child, found as an heirloom in a Classic tomb, is compared to show the link between Preclassic and Classic meaning. Full article

Dorsal penile nerve block stands out as one of the commonly employed regional anesthetic techniques in children. Despite the large body of experience, failure rates are still significant. We included 20 children (median (SD) age of 73 (31) months) scheduled for circumcision without general anesthesia and secondary airway manipulation in a consecutive case series. Under ultrasound guidance and utilizing an in-plane needle guidance technique, the dorsal penile nerve block was administered with slight sedation, and spontaneous respiration was maintained in all cases. To investigate the underlying anatomy for dorsal penile nerve blockade, we dissected three cadavers. The primary study endpoint was the success rate of surgical blockade, meaning that the surgical procedure could be performed without additional general anesthesia and invasive airway management. The secondary endpoint was the requirement of analgesics until discharge from the post-anesthesia care unit. The primary endpoint was successfully met in all patients according to our strict definition without additional general anesthesia or airway manipulation. In addition, no child received analgesics until discharge from the recovery room. The anatomical investigation clarified the specific anatomy as baseline knowledge for an ultrasound-guided dorsal penile nerve blockade and enabled successful performance in 20 consecutive children where penile surgery was possible in light sedation without additional airway manipulation.

Understanding and addressing post-radical prostatectomy (RP) erectile dysfunction (ED) is of paramount importance for clinicians. Cavernous nerve (CN) injury rat model studies have provided consistently promising experimental data regarding regaining erectile function (EF) after nerve damage-induced ED. However, these findings have failed to translate efficiently into clinical practice, with post-RP ED therapeutic management remaining cumbersome and enigmatic. This disparity highlights the need for further standardization and optimization of the elaborate surgical preparation protocols and multifaceted reporting parameters involved in reliable CN injury rat model experimentation. Even so, despite its technical complexity, this animal model remains instrumental in exploring the functional implications of RP, i.e., surgical lesions of the neurovascular bundles (NVBs). Herein, besides cavernous nerve (CN) dissection, injury, and electrostimulation, multiple pressure measurements, i.e., mean arterial pressure (MAP) and intra-cavernosal pressure (ICP), must also be achieved. A transverse cervical incision allows for carotid artery cannulation and MAP measurements. Conversely, ICP measurements entail circumcising the penis, exposing the ischiocavernous muscle, and inserting a needle into the corporal body. Finally, using an abdominal incision, the prostate is revealed, and the major pelvic ganglia (MPG) and CNs are dissected bilaterally. Specific surgical techniques are used to induce CN injuries. Herein, we provide a narrative and illustrative overview regarding these complex experimental procedures and their particular requirements, reflecting on current evidence and future research perspectives.
